Hitting them with a hammer is just too low-tech and gross, for the PlexEraser PX-OE100E is the Dalek of drives and exterminates the data layer on most formats of recordable CD and DVD.
Plextor claims that it can also handle dual layer DVDs too. It then marks the disk to show that it has been been wiped, in case you didn't already know.
The process is slow. It takes a good three minutes to wipe one disk. So why not use a shredder or a hammer?
According to Plextor it is all about showing off your green criteria. When you wallop, or shred a CD, the act releases an organic dye which kills the environment and is therefore bad for babies and little cuddly furry creatures.
Plextor says that when it vaporises the data layer with its lasers, the die is kept sealed. We assume this is until you chuck the thing out and it ends up on a landfill full of other leaking disks. ยต
